When you're debugging a problem, one way to waste a lot of time is to make guesses about the problem without verifying them. As you research a problem, you'll naturally come up with theories about what's causing the problem. That's fine. If you think you know what the problem is, test it out. Use a breakpoint or modify the code in a way that can verify that this code is causing the problem. Only then can you be sure you are fixing the right code. Too often, developers start fixing the wrong code because they thing they know what the problem is but didn't test out their theory. This wastes time and effort and makes the debugging process much more difficult.
